LANTERN-WINDOWS AND THEIR OPERATING MECHANISM.

Specification of Letters Patent.

Patented Mary 14, 1912.

Application filed April 18, 1911. Serial No. 621,941.

T a all whom it may concern:

Be it known that I, \VILLiAM BAYLEY, citizen of the United States, residing at Springfield, in the county of Clark, State of Ohio, have invented certain new and useful improvements in Lantern-Windows and Their Operating Mechanism, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to the Construction of ventilators for building roots, usually terl'ned monitors or "lanterns, to the manner of assembling the truss members, to the manner of applying windows to thesides,

to the hinging of the windows, to the manner and direction of opening the windows, to the manner of operating a long line of such windows.

Heretofore, the framing of the truss members of a lantern has always contemplated a post on the outside on each side, against the outside of which, (and extending from under the cave of the lantern roof down to the main roof), window frames have been secured. These frames, have been constructed with the window sills raised about one toot above the main roof, this one foot raise being necessary on account of keeping snow from banking up, or rain from splashing up and over the sill. Sometimes these window frames have been divided up into short spaces between the trusses and narrow window sashes pivoted'on the vertical center of ea ch. These sashes have either been operated independently, or have been connected together and operated by one mechanism from one point. Each side of the lantern being operated independently, or a continuous window sash has been installed and hinged to the top of the lantern side, just under the cave of its roof and arranged to open outward at its lower edge. Neither of the above plans can get rid of this one foot height from the main roof to the window sill and therefore cannot take advantage 7 of the 7 whole height of the lantern side for ventilation or the admittance of light. And both of the plans mentioned above have the objection of opening out beyond the projection of the caves of the roof, and are liable to exposure to bail and other outside agencies, both in the. nature of tending to break the glass and to deposit on it soot and dirt washed from on the lantern roof. This invention contemplates the construction of the truss members of a lantern so that there is no post on best form to favor the supporting o the outside. The weight of the eave of the lantern root being taken by an inclined post that carries the weight to a point higher ping of the hinge point down close to a main roof, andv in this way gaining a foot in height. This gain of a foot can be made use of in two ways, to gain more ventilation to allow the making of the windows higher, or if the ventilation is considered sufficient, then the lantern can be lowered in height and consequently lessened in cost. The V on the bot-tom of the window sash is made sufliciently angular to allow the sash to be opened inwardly at the top to the desired position. .The inclined-post that has been mentioned is placed high enough to clear the top edge of the window sash as it opensinwardly on a radial line from the hinge center. And. any braces in the structuralpart of the lantern truss are kept out of the way of opening the window sash inwardly. Then the points gained over the old construction are more ventilation and light, or the same ventilation, for less height, Complete protection from ordinary outside agencies of breakage; Complete protection from dirt deposits and soot from off of the lantern roof, and more light with the same area of sash not only because of more cleanliness, but because it is practical to construct the roof of the lantern with less overhanging cave, and in this way the light can pass more directly down throu' h the opening.

In the'framing o' the window sash, a 2 bar has been used at the bottom, it bein tlfie t e glass and the intermediate bars of the sash,

it has fingers riveted to it to make the V hinge point. At the top of the sash a strong angle has been used, strong enough to resist the bending strain from the wind pressure on the outside and between the lantern trusses. ind under thp cave of the lantern roof, a s rong purlin" is located, against which the top of the window sash closes. There is no chance for the window to leak at this point. Located and pivoted on each otherlcg ot' the crank, has'pivoted into it. a

clamp for a cable. The arrangement is such that the cable runs lengthwise through the lantern, and there is a strut running fronr truss to truss, adjacent to the bell crank centers to resist the pull of the operating cable.

In the drawings Figure 1 represents a view of the top of the main truss with Ian tern extension built on, it shows the roof bet-ween the trusses with its purlins in section, it shows the strut at the bell crank centers in section, and also the sash in section. Fig. 2 is an inside view of the window sash and a section of the truss on the line M M M M M M projected from Fig. 1. Fig. 3 is an enlarged section of the window sash with hinge and cap. Fig t is a section across the entire lantern between the trusses on the line T T, Fig. 9, it shows the window sashes open and shows the ventilation currents. Fig. 5 shows a plan of the bell crank with its motion and its connection to the window sash and to the cable, it

shows a section of the truss member on S S,

and is projected from Fig. 1. Figs. 6, 7, 8, show plan, side, and end views respectively of the cable clamp.

The numeral 1 represents the top chord of a main truss, 2 is the inclined post of the lantern truss, 3 is a brace in the lantern truss, 4 is a top chord of a lantern truss, 5 is a purlin of its main roof, to the side of.

which a strip 5 is secured and support the the sheathing 5". On the top of purlin 5, flashing. 6 is laid and clamped down by the hinge angle 7, which angle runs continuous along the roof, 4 is the sheathing of the lantern roof, 4: are'the comb purlins of the lantern roof and'SS is an eave purlin of the lantern roof, the eave purlin 8 supports the root, and also makes astrong cap for the window top 9 to close against, at the bottom of the window sashes is 'a 2 bar 10, this Z bar-has fingers 10 riveted to it. The 2 bar lO'and itsfinger 10 form a V that rests on the hinge angle 7. The 2 bar 10 and the top angle 9 are connected by vertical T win- 4 dow bars 11. The bottom end of the head of the T bar 11 is bent out into knee 11 and rivets on top of the 2 bar. The top end of the T bar is also ofi'set and rivets against the back of the angle 9. In this way the under side of the head of the T is brought flush or in line with the side of the angle 9 and the Z 10, making a fiat surface for the glass tolay against and be puttied in.

This invention does not comprehend any special way of securing the glass 12 into-the sashes. When the window is shut as shown in-Figs. 1, 2, 3, 9, 10, the center of gravity is outside of the hinge. point 7, (see Fig. 3) and the disposition is to remain closed unless wind should press against the sashes. And in order to hold the sashes shut and also to open them when necessary. At each truss along the building, bell cranks 13 are pivoted to the braces 3, and to angle struts 14, by knees 14", and a pin 15. The end ll of the bell crank 18 is connected by two pins and a knuckle joint 16 to the rod 17. And the'rod 17 is also connected by two pins and a knuckle joint 16 to knees 18, which are riveted to the top 9, of the window sashes. Thus the connection between the bell cranks to the window sashes is established, and if the bell cranks work in unison, then the sashes will be held close throughout their entire length and will be opened evenly. And to do this,-at the end W of-the bell crank 18, a clamp 19 is pivoted, clamp 19 consists of the back 19 which is pivoted into the .bell crank permanently, and the cap 19 which is bolted to the back 19 by the bolts 20. The cable 21 is stretched taut .through the building from end, to end, and through its connection with the bell cranks,

operates the ventilator windows.

Having fully described this invention, what is claimed as new and desired to secure by Letters Patent, is:
